Axial patterning of the chondrichthyan pharyngeal endoskeleton and the origin of the jaw
… patterning mechanisms within pharyngeal arches – embryonic structures which contain the progenitors of the jaw and gill arch skeleton – as well as unique transcriptional features that may underpin distinct jaw and gill arch morphologies. The latter include unique gene expression features of jaw …

Transgenic use of SMAD7 to suppress TGFß signaling during mouse development
… tube, migrate and contribute to a vast array of embryonic structures, including the majority of the head, the septum of the cardiac outflow tract (OFT), smooth muscle subpopulations, sympathetic nervous system and many other organs. Anomalous NCC morphogenesis is responsible for a wide variety of …

Automation of Single Cell Micromanipulation and Microsurgery for Blastocyst Embryo Biopsy
… A computer vision algorithm identifies the embryonic structures to estimate its orientation coordinates and uses this information in the vision feedback control system. The second step ablates the embryo ZP. Using the embryo structures identified in the previous step, a vision feedback …

Developmental and Cellular Functions of Delta-Catenin
… most adult Xenopus tissues, although enriched in embryonic structures of neural fate as visualized using RNA in-situ hybridization. To determine delta-catenin’s requirement in amphibian development, I employed anti-sense morpholinos to knock-down gene products, finding that delta-catenin depletion …

Human oocytes and embryos viewed by time-lapse videography, and the development of an embryo deselection model
Despite its wide application today, in vitro fertilization (IVF) treatment continues to have relatively low efficacy, largely due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse …

Light Sheet Microscopy and Image Analysis of Neural Development and Programmed Cell Death in C. Elegans Embryos
… embryos as important central nervous system structures are being created may yield novel insight into the role of distinct cell groups in creating these structures. New developments in microscopy have made this an excellent time to study neural development in the C. elegans embryo. In the …

Effect of Thyroid Hormones on AT1R MRNA Levels in HEK 293 Cells: Implications for Early-Onset Hypertension in Children Born of Preeclamptic Women
… II type 1 receptor mRNA levels in human embryonic kidney cells (HEK). Maternal preeclampsia is a prediction of higher ambulatory blood pressure (ABP) in the exposed offspring. The mother's blood pressure affects the blood pressure of the fetus since the placenta mediates blood flow. …
